Definitions

the invention relates to a plug arrangement for gas-tight sealing of a Cell opening of an accumulator, formed from one in the cell opening sealing plug can be used.
Accumulators are known per se from the prior art. They exist from different electrodes, provided the accumulator is multi-celled is carried out, combined into individual cells and in one housing are arranged. The top of the housing is closed with a lid. The housing cover usually consists of an upper and a lower cover, with a cavity for acid separation between the upper and lower cover is trained. An accumulator of this type is described, for example, in EP 0 584 528 B1.
the electrodes are usually used for motor vehicles
Lead accumulators made of lead are designed in the form of a grid, the mesh of the grid on the positive side with lead oxide and on the negative side with so-called lead sponge are filled.
As an electrolyte as a rule Sulfuric acid is used, either in liquid or in the manner of a gel thickened form can be used. It happens during charging chemical reactions in the electrolyte, which also lead to a Lead gas evolution.
the accumulator has for degassing Gas outlet openings. These are mostly formed in the area of the cover.
easily flammable gases are from the state of the Technique known two basic degassing options.
the gas discharge takes place in such a way that the gases directly over the individual Stopper closing cell openings to the surrounding the accumulator Atmosphere.
Such a gas discharge is known for example from EP 0 756 338.
the gas discharge can a central degassing line. With this degassing variant they are individual cells of the battery over a common, mostly in Battery cover integrated degassing line running across the cells connected with each other.
Gases to be discharged are via the degassing line mostly carried out on the front side of the housing cover from the battery cover and released into the atmosphere.
the latter is known Degassing variant, inter alia from EP 0 305 822 A1 and US 5,561,001.
gases to be discharged before exiting the accumulator through a porous Filter disc, the so-called frit This serves in particular the Avoiding reignitions of the highly flammable gases back into the Accumulator inside.
the invention is therefore avoiding the disadvantages mentioned above Task based on specifying a stopper arrangement that is sufficient Degassing enables and at the same time leakage of acid even with one Tilting or rotating the accumulator largely prevented. Furthermore, the Plug arrangement can be produced economically, is easy to install and on different types of accumulators can be adapted.
the invention proposes a Plug arrangement for gas-tight sealing of a cell opening Accumulator formed from a sealable insert into the cell opening Sealing plug, the inside of the cell for acid separation using a a two-way sealing membrane provided opening in the lateral surface of the Sealing plug fluidically with a between upper and Lower cover of the housing cover is formed in connection.
An accumulator provided with the plug arrangement according to the invention is with regard to the leakage of acid against twisting or tilting movements largely insensitive.
the opening in. With a sealing membrane the outer surface of the sealing plug allows degassing Accumulator cells, but it effectively prevents unwanted acid from improper handling or as a result of assembly-related Angled position emerges from the inside of the cell and into the inside of the housing cover trained cavity runs.
the two-way sealing membrane also enables the slow reflux of acid in the event that due to excessive Internal pressure, for example in the event of overloading, during the degassing process Acid from the cell gets into the cavity of the housing cover. The Acid can then collect in the cavity, the sealing membrane in reverse Passing direction, over the in the outer surface of the sealing plug formed opening flow back into the interior of the cell.
the sealing membrane is on at least one Provide an opening to form a passage opening. Consequently is advantageously ensured on the one hand that gas during a Degassing can emerge unhindered from the inside of the cell that on the other hand also acid present in the cavity of the housing cover can get back inside the cell. Thus, both in the cavity separated acid as well as due to twisting or tilting of the Accumulator accidentally penetrated acid back into the cavity Headed inside the cell.
the gap-like has proven to be particularly advantageous Formation of the breakthrough highlighted.
the sealing membrane is made of two each flexible partial membranes formed on one side.
This kind of Training advantageously allows both the gas outlet and the Recycle acid accumulated in the cavity.
the partial membrane in the direction of Cavity pivotally arranged. This arrangement advantageously supports Way the degassing acting towards the cavity. The due to the enable two-part arrangement of the sub-membranes formed columns the slow reflux of the im Cavity accumulated acid. Due to the flexible training of the Partial membranes is also advantageously clogged by the Sealing membrane closed opening by particles that dissolve in the cell can prevented, so that a safe degassing under all operating conditions of the accumulator is possible.
the surface of the Sealing plug formed in an opening in the cell opening inserted plug opposite the cavity access arranged ensures that at a ready-to-use accumulator which is formed in the sealing plug Openings are always positioned in such a way that on the one hand an unobstructed Degassing and on the other hand a possible acid recirculation can take place.
the lower edge is that in the Shell surface of the plug formed opening below the Lower edge of the cavity access opening arranged. This ensures that both the acid flowing into the cavity and that in the cavity trained condensate accumulates directly in front of the lock-like sealing membrane and gradually flows back into the interior of the cell. Residues in the cavity are therefore avoided.
the plug has a circumferential seal on the head, which in the case of one in the cell opening used sealing plug in the area of the upper cover sealing the Surrounding the cell opening and the cavity opposite the seals the atmosphere surrounding the accumulator.
the circumferential seal is a round seal, preferably an O-ring.
the plug has also a circumferential seal on the foot side, which at one in the Plug inserted in the area of the lower cover sealingly abuts the wall surrounding the cell opening and the Seals the cavity from the inside of the cell.
the circulating Seal preferably designed as a lamellar seal.
the advantage of one Lamellar seal lies in particular in the fact that tolerances between the Cell openings of the lower and upper lid can be compensated so that tolerance compensation when joining the top and bottom covers Center position offset is enabled.
Two-way sealing membrane also ensures that in addition to degassing the Inside the cell, there is also a return of condensate and / or into the cavity acid that has run in is possible.
both the round seal and the lamellar seal is also integrally formed on the sealing plug.
the sealing membrane also in one piece Shaped stopper, the round and lamellar seal and the Sealing membrane in a two-component process using injection molding in one single process step.
One in the aforementioned way manufactured sealing plug can by slight modifications in shape and Size can be varied so that according to the modular principle different Sealing plug for adaptation to different types of accumulators are producible.
they are integrally molded with The sealing plug provided with sealing elements is easy to assemble.
